Abstract:Qibaoshan polymetallic deposit in Wulian county is the largest polymetallic deposit in Shandong province. The discovery of the deposit is attributed to the change of traditional prospecting ideas from prospecting for cryptoexplosive breccia type goldcopper deposit to prospecting for PbZnAgCu polymetallic deposit controlled by faults. Through analysis on the discovery and exploration history of deposits, it is important to break through traditional ideas of ore prospecting, make full use of geophysical and geochemical data, effectively play the role of "capital + technology", and evaluate deposits according to local conditions.
